“By challenging this merger, the Department of Justice is saying that the American people deserve better,” U.S. Attorney General Eric Holder said in a statement. “This transaction would result in consumers paying the price—in higher airfares, higher fees and fewer choices.”

According to Bloomberg, the DOJ wanted the trial set for February, but the airlines are pushing to get a November trial date—claiming in a joint filing that putting it off would “cause serious harm and cannot be justified.”

The airlines say the suit is an obstacle in AMR’s plans to exit bankruptcy. “The parties’ urgency to complete their transaction is far greater here than in ordinary merger cases,” the airlines said. “American’s ongoing bankruptcy proceedings compound the costs and uncertainties associated with the delays caused by the government’s lawsuit, including approximately $500,000 in bankruptcy-related professional fees alone every day that the bankruptcy continues.”
